That function could massage incoming text fields and convert spaces to
hyphens or underscores, but I'd assume the right place to do it would be
in the original text.  If you suggest the former, it could just be done
in audit_log_string(), but then grepping the source for error messages
would not be nearly as useful.  Is this what you were suggesting?
